This paper presents a miniaturized microstrip antenna for Super Wide Band (SWB) (3–40 GHz) applications. The antenna consists of two asymmetrical annular rings where the first ring is connected to the feed line and the second ring is a gap coupled within the first ring. In addition to this, four stubs are connected with the antenna’s radiating element. To obtain the SWB, three circular slots are cut in the ground structure. The dimension of antenna is 16 mm × 16 mm × 1.6 mm. FR4 is used as dielectric material which has dielectric constant 4.4 and loss tangent 0.02. As the result shows the maximum gain of the antenna is 2.8 dBi. In case of VSWR ≤ 2, the bandwidth ratio and percentage bandwidth are 13.3:1 and 172%, respectively.
